[dpdk-stable] [PATCH 1/2] app/test: uninit vdevs in event eth Rx adapter autotest

[Jayatheerthan, Jay]

From: "Jay Jayatheerthan" <jay.jayatheerthan@intel.com>

adapter_multi_eth_add_del() does vdev init but doesn't uninit them.
This causes issues when running event_eth_rx_adapter_autotest multiple
times.

The fix does vdev uninit before exiting the test.

[dpdk-stable] [PATCH 2/2] app/test: add net null dev creation in Rx adapter autotest

[Jayatheerthan, Jay]

From: "Jay Jayatheerthan" <jay.jayatheerthan@intel.com>

Allows creation of net_null if vdev EAL option is not specified and
uninit vdev created in the test. The change also adds error checks
for vdev init and uninit.
